this study was conducted for evaluating the combined effect of soil moisture, phosphorus (p) and zinc (zn) levels on the growth attributes of potato (solanum tuberosum l. cv. agria). this investigation was arranged as a factorial experiment based on randomized complete blocks design with zn at three levels (0, 10 and 20mg zn per kg dry soil as zinc sulfate), p at three levels (0, 30 and 60mg pe...

Among Australian fungus-feeding Thysanoptera, five new synonyms are recognised in Horistothrips Morgan, and among leaf-feeding species, three new synonyms are recognised in Teuchothrips Hood and one in Neocecidothrips Moulton. Horistothrips curviseta Girault is transferred to Neocecidothrips as the second species in that genus and its host-plant is identified. Cryptothrips additamentus Karny is...

The long-distance movement of cherry leaf roll virus (CLRV) in tobacco plants was studied using a tissue printing technique with non-isotopic RNA probes. Time-course analysis revealed that CLRV RNA accumulated in the inoculated leaf at an early stage, such as 20 h post-inoculation. The virus accumulation reached a peak at 8-10 days post-inoculation (d.p.i.) and then progressively decreased. The...
